When the body temperature monitoring sensor (32) monitors that the temperature of the human body temperature measuring sensor (22) is greater than or equal to t max, the temperature regulator (342) refrigerates the heat conduction module (341), the heat conduction module (341) conducts heat from the human body temperature measuring sensor (22) to the refrigeration module, and the refrigeration module transfers the heat to the air through the heat exchanger (343) to realize the cooling of the human body temperature measuring sensor (22) until the value of the body temperature monitoring sensor (32) reaches (t min+tmax)/2;
a fan (344) is arranged on the heat exchanger (343).
